Secure communication method and system of wireless BMS (Battery Management System) and storage medium

Abstract

The invention discloses a secure communication method and system of a wireless BMS (Battery Management System) and a storage medium. The method comprises the following steps: receiving an encrypted message sent by a main node; decrypting the encrypted message to obtain an original message; the original message is verified according to a preset verification algorithm to obtain a verification result, and the preset verification algorithm comprises one or more of a cyclic redundancy verification algorithm, a counter verification algorithm, a message length verification algorithm and command execution range verification; if the verification result is successful verification, executing the target command in the original message; and if the verification result is verification failure, discarding the original message. According to the invention, the slave node decrypts the encrypted message to obtain the original message, verifies the original message, and executes the target command in the original message only when the verification succeeds, so that information leakage and tampering are avoided, and the communication security is improved.
